Description Ian Henderson 2011-06-07 19:30:36 PDT

When drawing sub-images in BitmapImage::draw, we clip to destRect, then draw into adjustedDestRect.  If they're the same, we could avoid clipping and just draw the image.

I think this caused some pixel changes for SnowLeopard. The changes seemed fine to me so I commit them in r88325 if you wanted to verify.
